IMPROVEMENT IN HINGES FOR SAFE AND VAULT DOORS.

Specification formin g part of Letters Patent No. 144,669, datedNovember 18 1873; application filed August 9, 1873.

door, outward, thereby drawing the interlocking flanges of the door andthe jambs apart, preparatory to turning the door 011 its hinges, ashereinafter more fully described.

Figure 1 is a front elevation of my improved hinge with its operatinglever. Fig. 2 is a horizontal section of the same on the line a; a: ofFig. 1, together with a portion of a safe hav- 1 1 ing the hingeattached. Fig. 3 is a horizontal section of the upper leaf onithe lineyy of Fig. 1. Fig. 4 is a top plan View of the lower leaf.

In the drawings, B represents the lower leaf, which is made of the formshown in Figs. 1 and 4, with a vertically-projecting pintle, D. The

upper leaf, A, is provided with a slot, K, having its longer axisstanding at right angles to the face of the wall to which it isattached, and of the proper size for the pintle D to slide freelytherein, as shown in Fig. 3. This leaf A is provided, at its lower rearedge, with a vertically-projecting lip, J,which is curved on its innerface, so as to fit down over the edge of an eccentric, O, which isformed on the end of a lever, E, that is pivoted on the pintle D,

, between the two leaves, as shownin Figs. 1

and 2. a

From this description, it will be seen that when the lever E is drawnback or swung outward, the eccentric G will be turned on the pintle D,and its outerface, bearing. against the inner face of the lip J, willcause the upper leaf, A, to move outward in a right line,

the slot K permitting it to thus move on the pintle D, and thismovement,of course, carries the door out with it far enough to disengagethe interlocking flanges and recesses H and I of the door andjambs,after which the of the lip J, and thereby forces the door in to 1its place, and interlocks the flanges and rece'sses, as representedinFig. 2.

By this mode of construction I provide a very simple and eificienthinge, and means of operating the same.v

' Having thus described my invention, what Iclaim is- 3 1. A hingeconsisting of theleaf B with its pintle D,and the leaf A provided withthe slot K and lip J, in combination with the eccentric O, the saidparts being constructed and arranged to operate substantially asdescribed.

2. The lever E provided with the eccentric G, in combination with thelip J on the leaf A, the whole being constructed and arranged to operateas set forth.

In testimony of which invention I hereunto set my hand.
